After recent heavy rains, had static on the AM stations. Pulled the antenna, dried and cleaned the threads and used dielectric grease.

Was slightly improved,still need to find a better answer. Maybe the antenna cable itself has water inside, or a bad ground somewhere? Or some kind of resistor or ???

Suggestions/ exeperiences most welcome.

Usually static, on an AM station, is because of a poor antenna ground.
But, you could be picking up electrical sparking from other sources. Try it without the engine running and turn off HIDs if you have them.

That's what I was thinking, ground or the antenna cable itself had poor connection made worse from the rains.
Thanks
